Degreasing should be considered a first step in stencil-making, as it greatly reduces the risk of stencil-making failure, extends on-press stencil longevity, and alleviates pinholing. Ulano Screen Degreaser Liquid No. 3 is ready-to-use--no mixing. Ulano degreases effectively in hard water. Rinses clean with hot or cold water. Non-caustic--will not harm frames, mesh, or adhesives on stretch and glue frames. Reccomended for use with all Ulano stencil systems.
